I might be wrong about some of the implementation details, but here's what seems to happen in most hotels (at least the bigger ones) these days: if an unknown device connects to the (open) network, any traffic from that device but TCP port 80 is dropped; TCP port 80 is sent to a local web interface. Once the user logs in on that interface, the device is recognised and future requests, regardless of protocol and port, are sent to the open Internet. I've used that in three different hotels in the past week. Once logged in, I was able to connect my laptop to the company's VPN without any issues.
